Technical Details

This is the family description for the Adware:W32/Gator family of adware programs.

This adware family is associated with the Gator Corporation (since renamed to Claria Corporation, now no longer in operation) and its GAIN advertising network. Please refer to Claria description for a more detailed overview of the nature of this network.

Installation

Adware:W32/Gator variants are primarily components of a Gator-related adware program known as Trickler, which downloads these additional components to the affected system. Trickler is itself most likely installed by being bundled with third-party software.

During installation, Gator variants use registry Run keys as a launchpoint. They also commonly use the %temp%\fsg_tmp directory for storage of temporary files.

Activity

While active, the adware program attempts to connect to remote servers, most likely to retrieve advertising materials. Some representative connection attempts are:

  • gs.gator.com
  • gi.gator.com
  • trickle.gator.com

Registry

Gator adware programs may create the following mutex to ensure only one copy is active at a time:

  • Global\TricklerRunningMutex
